Deno

👀 Getting Started

Adding BugSplat error reporting to your Deno application, web worker, or serverless function only takes a few lines of code. Once integrated, BugSplat will capture stack traces, logs, and other valuable insight when your code encounters a problem. BugSplat's bugsplat-js package is fully typed and easily imported via esm.sh.

⚙️ Integrating

Add an import from bugsplat-js via esm.sh:

import { BugSplat } from 'https://esm.sh/[email protected]';

Create a new instance of the BugSplat class with the name of your BugSplat database, the name of your application, and the version of your application:

const bugsplat = new BugSplat('DatabaseName', 'AppName', '1.0.0');

Use the bugsplat instance to capture errors that originate inside of try-catch blocks:

try {
  throw new Error("BugSplat");
} catch (error) {
  await bugsplat.post(error);
}

Use bugsplat to post errors from promise rejections:

Promise.reject(new Error("BugSplat!")).catch(error => bugsplat.post(error, {}));

You can also attach a file to your error post by passing a BugSplatOptions object containing with a value for additionalFormDataParams property.

await bugsplat.post(error, getAdditionalOptionsWithLogFile());

function getAdditionalOptionsWithLogFile() {
  const filename = 'log.txt';
  return {
    additionalFormDataParams: [{
      key: 'file',
      value: new File([Deno.readFileSync(filename)], filename),
      filename: filename,
    }],
  };
}

🧪 Sample

Clone the my-deno-crasher repository:

git clone https://github.com/BugSplat-Git/my-deno-crasher

Set your current directory to my-deno-crasher.

cd my-deno-crasher

Run the sample with the --allow-net and --allow-read flags to allow BugSplat to post an error to our backend and read the log file respectively.

deno run --allow-net --allow-read main.ts

📈 Viewing Reports

After posting an error, navigate to the Crashes page. You should see a new crash report for the application you just configured. Click the link in the ID column to see details about your crash on the Crashes page:

Deno Error Reports

Deno Error Report

That’s it! Your application is now configured to post error reports to BugSplat.

🧩 API

In addition to the configuration demonstrated above, there are a few public methods that can be used to customize your BugSplat integration:

bugsplat.setDefaultAppKey(appKey); // Additional metadata that can be queried via BugSplats web application
bugsplat.setDefaultUser(user); // The name or id of your user
bugsplat.setDefaultEmail(email); // The email of your user
bugsplat.setDefaultDescription(description); // Additional info about your crash that gets reset after every post
async bugsplat.post(error, options); // Posts an arbitrary Error object to BugSplat
// If the values options.appKey, options.user, options.email, options.description are set the corresponding default values will be overwritten
// Returns a promise that resolves with properties: error (if there was an error posting to BugSplat), response (the response from the BugSplat crash post API), and original (the error passed by bugsplat.post)
